Gerry Goffin and Carole King wrote Up On The Roof under the influence of another famous songwriting duo: Doc Pomus & Mort Shuman, influenced by the way they wrote Save The Last Dance For Me, more precisely: the way The Drifters recorded that one. Goffin & King wanted to write for The Drifters as well. First they gave 'em Some Kind Of Wonderful, later Up On The Roof. A try-out was performed at home by their babysitter, soon the world's most famous babysitter.
